I agree in large with with Newflyer on the grounds that (potentially) spurning these developers could spurn future developers.
Of course, this is an embryonic statement, but I would definitely want to formally weigh the pros and cons of saving the buildings & possible draw-back in future investment/developers before diving head first into the save the building project. I guess I take a Dan Vandal stance ...bad until proven good, but will give it ample opportunity to prove good.
